as generally indicated by the numeral l5. lAs'Wll lhe apparent froinFig. l1, the `plaster may extend v t y down to' .the face of` the bottomY member I of v.the 'Flgurel is a vertical sectional view taken ce-nreceptor. .The shower stall walls Tm'ay then be tiled oriinished in "the usual manner 'and the vtiling'or iinishing H5 may also 'extend tovthe face 'of the bottoinmemher i.' lThis guardspositively v t against lateral leakage.

this isprevented; for whatever water leaks through the stall walls iti-lli will be intercepted 'bythe receptor` sidewalls 2 and `will beV guided downwardly along the inner face thereof and 'be directed to the bottom. member l where ituwill be .drained off v'through the vusual sewer drain l1.

Such lealrages' are yconilned substantially `to the lower part of the stall walls and'rny improved re'- ceptor takes care o'fthis.-

f For the purpose of guidingwat'er andcondensa'- tion down the inner sides of the walls 2, the inner faces are inclined inwardly toward the bottom, as is apparent from Fig. 1.

In producing my improved receptor, I employ a mold 2| such as is shown in Fig. 4, and build up or preform my receptor in the following manner:

First I centrally perforate the rubber mat or sheeting '4 and fasten it to the drain structure and lockit in position against the flange l0. by tightening the lock-nut washer I9. `I then place the metal lath 3 in each of the side wall cavities 20, and then ll the cavities 2B with pure asphalt. The rubber matting 4 is then placed top'face down in the mold. The mold 2| is next substantially filled with the composition herenbefore described..

While the composition is still in liquid form,A

the insulation board 6, having first been appropriately cut out centrally to provide for the drain structure, is then placed in the composition` close tothe surface` j The mold then is Ai'llled with pure asphalt flush with the top and smoothed o;

floor to safeguard a shower bather from slipping.

When constructing a new building, Where shower stalls are to be provided, the usual sewer vdrain i7 is customarily set in the-center portion of the shower stall, so 'that when installing the receptor it is only necessary to set the same on the oor beams or sub-flooring as the case may be. I

vIt is also customary to remove the drain cover plate I2 temporarily and fill the portionaround the protruding upper end of the drain vwith a water-proofing filler material 22; suchy as caulking compound and lead or the like, and for this purpose I have provided an inwardly extending flange 9 on the sleeve 8 to act as a form for retaining the filler material.

It will be seen that shower stall walls may vary in thickness as the receptor is built to conform substantially to the standard spacing of the studs I4 and not to the spacing of 'the inside faces of the shower stall walls. It will also be seen that the entire `lower part of the shower stall walls is located Within the receptor walls, so that in the event of water seepage through-the tiling -joints or cracks in the shower stall walls, the water seeping through will be caught in the receptor. being seamless and also being sufficiently flexible, due to the material from which it is made, cannot crack or leak at any time. The tread on the rubber matting provides a slip-proof safety feature. 'I'he edges of the rubber mat 4 are waterproofed and held in place by being setl in the asphalt, as at 23. matting, holding it down.` The lower edge of the plaster l5 and tiling I6 bears thereon.

Another advantage of the present receptor is that its weight is cut down to a minimum and the receptor is a great deal lighter than receptors heretofore used or on the market today, `and therefore easier and less costly to install. Also, as will be apparent, the vcost of producing this unit is relatively small'due to the low cost of the materials used. VMetal receptors and Waterproofing shower stall pans arealways subject to The receptor,

The asphalt adheres tothe rusting and other chemical oxidizing action;

therefore, they are always constantly subject to leakage. It will therefore be apparent, because of the materials used in my improved receptor,

It can also readily be seen that it is not, especially essential'to incorporate the slip-proof rubber matting in the unit when vit is molded; but

because of its desirability, it. canbe applied to is perthe floor after the receptor is installed, thereby "i making it removable and renewable at any time.

It is also to be understoodthat any other suitable` material may be substituted for this rubber matting, if desired, Without departing from the spirit of the'invention, as 'it isv to be understood that `:floor tiling might readily be substituted therefor if another type of floor covering is demanded.

It should also be understood that the side Walls of the receptor may be-,formed of any waterproof material, such as -metal or concrete, but that in order to insure that the Vspirit of this invention. is not lost, the walls, regardless of the material,` should be molded to the bottom .member and be substantially integraltherewith in effect.

It should be understood that the asphalt or a composition including asphalt could be altered or changed Without departing from the spirit of this'invention, as long as asphalt orother material having the properties and characteristics of asphalt whichl arev necessary in'making waterproof shower receptors is used as awater-proofing, molding, or bonding material in) making shower receptors.
